ADSL line down - Terrible servicee

My Internet (ADSL line) connection has been down since Tuesday 12 December 2017, and yet to date no proper feedback has been provided. After getting enquiry calls and sms's stating that a technician will investigate, to date none has been done. Telkom cannot tell me where the fault actually lies, and no technician has come out to the exchange server in the area nor has anyone come home. It has taken over 4 days for the issue to be escalated to another department and yet nothing has been done. I am now told that the issue will be looked at on 3 January 2018. I know that it is year end but surely there is technicians available during the working days to have a look at the fault. This is just another issue that I have been encountering problems with all year, from line connectivity issues to line speed problems , etc. And i am being billed every time without any compensation. This is totally unacceptable.
